COMBINED RHEOSTAT AND SOCKET.

Application filed April 4,

To all whom it may cmwem:

Be it known that we, CONRAD KLEMMER and -\VAL'I'ER P. Koecnnt, citizens of the United States, residing at Bogota, N. J., in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Combined Rheostats and Sockets, of which the following is a specification.

This invention relates to a combined socket and rheostat unit and more particularly to a novel and improved device adapted particularly to be mounted on the panel of a radio outfit without resorting to the use of separate fastening elements or mount;

in s.

he primary object of the invention is the )rovision of a vacuum bulb or tu e holding socket which is connected to an insulated block or support so that it combines with the same to comprise a unit whereby the same is attachable to a panel'and arranged so that the conductors leading to the positive and negative filaments may be easily connected as is common in various types of radio receiving outfits.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and ointed out in the subject matter being c aimed, it being understood that various changes in the form, proportion, size and minor details of construction may be resorted to without departing from the spirit and scope of the invention.

In the drawings, Figure 1 is a front view of the rheostat mounted in the panel.

Fi re 2 is a side view showing the combine socket and block or support connected up and attached to the panel.

Figure 3 is a rear view of the rheostat.

Figure 4 is a vertical sectional view through the block or support as shown by Fi ure 2.

igure 5 is a plan view and,

Figure 6 is a detailed view showing the connection between the socket and the block.

Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, 5 desi nates the panel and 6 the graduated dia? thereon of any conventional type of radio outfit to which the combined rheostat and socket are to be mounted. A

.ldly maintaining the same in position.

Reference being had in particular to Figure .6, it will be observed that the block is pro vided wQth a pair of spaced recesses 13, 14 wh ch receive the supporting arms 15, 16 formed integral with the lateral extension .17 of the annular W. T. radio bulb supporting socket 18. By reason of this construc tion it will be readily seen that the arms 15, l6-may be forced into the recesses 13, 14 in such a wa as to properly support the said socket an thus result in a combined rheostat and socket unit attachable to the usual type of panel. The socket of course is adapted to receive the conventional type of V. T. radio bulb havin the positive and negative filaments, a ri and a plate which have been designate F+, F, G and P to which the conductors are connected as clearly shown by Figure 3 of the drawing. The screws and lock nuts 20, 21 maintain each resilient contact point 22 in position beneath the bottom of the socket so as to provide for the proper connection with the contact points of the bulb. One of the resilient arms 22 is bent u wardly as at 23' and secured by a screw and nut 24, the upper end of the said element 23 being bent slightly outwardly as shown at 25 and having an aperture whereby the rheostat rod 26 may extend therethrough. The rheostat serrated knob 27 is of course on the outer end of the rod 26, the said rod having a spacing collar 27 and the rotatable contact arm 28 thereon and held in position by the nut 29. The contact arm 28 of course may be bent inwardly as shown at 30 to ma e contact with the resistance coil 8 so that by simply rotating the knob 27, the said contact arm may be moved either clockwise or anti-clockw1se with the pointer 32 moving circumferentially of the dial.

Particular attention is directed, however. to the unitarv structure of the socket 18 and the manner in which the same is mounted in the rertangularibloclr or support 7' so that, additionai fastening elements or supporting and mounting devices are avoided vyherehy the said socket may be held in position in its proper relation with the resilient contact points 22 as above set forth. In order to permit of the proper rotation of the. rod 2t] and the contact arm 28, it will be observed that the top portion of the extension 17 ls provided with a substantially U shaped recess 33 and consequently the above permits of the movement of the said contact arm 23 to its maximum position on the scale.

Having thus described our invention, what we claim as new and desire to secure by United States Letters Patent is l. device of the class described comprising a common insulated support, a rheostat, a bulb mounting secured in the support and constituting a unit with the rheostat, and means for securingthe support we panel,

A device of the class 'deseribed'comprising an insulated rheostat use, a rheostat. a vacuum bulb mounting rign iny held in the base in proximjtyto the rheostat and cunstitutinga unit therewith, and means for securing the support to a pane 3. A device of the class described comprising an insulatedrheostat base, a rheostat, a vacuum bulb mou-ntin having a lateral extension rigidly secure of the base anddrspo'sed'so that the contact points of the vacuum b'nlb will make proper 'in the bo y contact with thqeqntact, arms the rheostat, and means or securing the base to a panel.
